Version 1.5.4
GENERAL PRECAUTIONS

Keep the unit more than 1 m (3.3') away from radio or TV.

Keep the intercom wires more than 30cm (12'') away from AC100-240V wiring. AC induced
noise and/or unit malfunction could result.

Install the unit in an area that will be accessible for future inspections, repairs, and
maintenance.

As to other manufacturer’s devices (such as door releases) used with this system, comply with
the Specifications and Warranty conditions that the manufacturers or venders present.

If the unit is down or does not operate properly, unplug the power supply.

The unit can be damaged if dropped. Handle with care.

The unit turns inoperative during power failure.

In areas where broadcasting station antennas are close by, the intercom system may be
affected by radio frequency interference.

All the units are designed for indoor use only. Do not use outdoor.

This product, being a control unit of door release, should not be used as a crime prevention
device.

It must be noted in advance that the LCD panel, though manufactured with very high precision
techniques, inevitably will have a very small portion of its picture elements always lit or not lit
at all. This is not considered a unit malfunction.

Door station is not weather-resistant, and do not spray with high pressure water. Unit trouble
could result.

For wiring, specify CAT5e straight cable.

Due to the environmental sound around the unit, it may hinder smooth communication, but
this is not a malfunction.

When outside temperature lowers sharply after rainfall, etc., the inside of camera may fog up
slightly, causing a blurry picture, but this is not a malfunction. Normal operation will be
restored when moisture evaporates.

Do not locate the units in a location with restricted access. It impedes maintenance inspection
or repairs. Also, unit trouble could result.

If the wrong power supply is used it could damage the product(s) and will void your warranty
on the product.
System Configuration and Connections

The system is a video intercom system especially designed for applications in facilities such
as office buildings, factories, schools, hospitals.

Installed separately from conventional general-purpose internal communications systems, the
system can be used as:
◦
a video door entry system,
◦
emergency announcement system,
◦
rescue assistance system, urgent call system,
◦
public announcement system, and access control system.

The system can be constructed on an IP network so multiple sites of system can be
connected and controlled as a global system. You can design the system to any scale
depending on your needs.
